Description
DESCRIZIONE dell’invenzione industriale avente per TITOLO: DESCRIPTION of the industrial invention with TITLE:
SISTEMA di CONVERSIONE ELETTRICA della ENERGIA EOLICA con ELICHE CONTROROTANTI e GENERATORI ad ALBERO CAVO ELECTRIC CONVERSION SYSTEM of WIND ENERGY with COUNTER-ROTATING PROPELLERS and HOLLOW SHAFT GENERATORS
“AEROGENERATORE VOLANTE AD ASSETTO VARIABILE”. “FLYING WIND GENERATOR WITH VARIABLE TRIM”.
Prima di procedere alla descrizione della invenzione è opportuno puntualizzare che per ragioni di chiarezza dei disegni, che devono per forza rientrare nel piccolo formato A4, sono stati omessi una serie di particolari meccanici usuali in ogni costruzione meccanica ma che nella fattispecie avrebbero solo complicato la comprensione del vero aspetto innovativo del presente trovato. Before proceeding with the description of the invention, it should be pointed out that for reasons of clarity of the drawings, which must necessarily fall within the small A4 format, a series of mechanical details which are usual in any mechanical construction but which in this case would have only complicated the understanding have been omitted. of the true innovative aspect of the present invention.
In particolare i disegni allegati sono stati compilati secondo le seguenti regole: In particular, the attached drawings have been compiled according to the following rules:
• I cuscinetti sono tutti radiali anche dove è evidentemente necessario porre cuscinetti obliqui o conici • The bearings are all radial even where it is obviously necessary to place oblique or tapered bearings
• Le guarnizioni non sono state quasi mai indicate • Seals were almost never indicated
• Gli alberi di trasmissione cavi coassiali (4),(5) e (11) hanno naturalmente bisogno di cuscinetti intermedi, non raffigurati nei disegni, che andranno posizionati ove i calcoli lo richiederanno in funzione della loro lunghezza effettiva e della velocità di rotazione definitiva • L’albero di trasmissione (11) che aziona i generatori (14) e (15) è stato raffigurato come pezzo unico anche se nella realtà sarà quasi certamente realizzato in almeno due tronconi meccanicamente collegati tra di loro • The coaxial hollow transmission shafts (4), (5) and (11) naturally need intermediate bearings, not shown in the drawings, which will be positioned where the calculations require it according to their effective length and the definitive speed of rotation. • The transmission shaft (11) that drives the generators (14) and (15) has been shown as a single piece even if in reality it will almost certainly be made in at least two sections mechanically connected to each other
Due eliche controrotanti (1) e (2) sono messe in rotazione dal vento ed azionano due alberi di trasmissione cavi coassiali (4) e (5). L’albero (5) aziona la corona di una gear box epicicloidale (8) che a sua volta fa ruotare le ruote satellitari (19) le quali ancora mettono in rotazione, a una velocità maggiore di quella della corona (8), le ruote solari (o pignoni) (7). Il pignone (7) mette in rotazione l’albero (11) che è solidale alle masse rotoriche (9) dei generatori elettrici (14) e (15). L’albero (11), come già detto, è raffigurato come formato da un unico pezzo mentre nella realtà costruttiva sarà formato da almeno due semialberi collegati meccanicamente tra di loro. Two counter-rotating propellers (1) and (2) are rotated by the wind and drive two coaxial cable transmission shafts (4) and (5). The shaft (5) drives the crown of a planetary gear box (8) which in turn rotates the satellite wheels (19) which still rotate the wheels at a speed greater than that of the crown (8). solar panels (or pinions) (7). The pinion (7) rotates the shaft (11) which is integral with the rotor masses (9) of the electric generators (14) and (15). The shaft (11), as already mentioned, is depicted as formed by a single piece while in construction reality it will be formed by at least two half-shafts mechanically connected to each other.
L’elica (1) aziona l’albero cavo (4) che attraversa coassialmente la gear box (13) e tutta la serie di generatori elettrici (14),(15),(16) e (17) di fig.1 fino a giungere alla gear box (18) ove si collega alla corona (8) che a sua volta, analogamente a quanto avveniva per i generatori (14) e (15) fa ruotare l’albero (20) (anche ora raffigurato in solo pezzo) e, di conseguenza, le masse rotoriche dei generatori (16) e (17) convertendo così la energia meccanica del vento in energia elettrica. The propeller (1) drives the hollow shaft (4) which coaxially crosses the gear box (13) and the whole series of electric generators (14), (15), (16) and (17) of fig. 1 up to reach the gear box (18) where it is connected to the crown (8) which in turn, similarly to what happened for the generators (14) and (15), rotates the shaft (20) (also now shown in one piece only ) and, consequently, the rotor masses of the generators (16) and (17) thus converting the mechanical energy of the wind into electrical energy.
Si rammenta che nei disegni l’albero (4) non poggia su cuscinetti intermedi ma solo sui cuscinetti finali del riduttore (18) anche se nella realtà andranno obbligatoriamente previsti cuscinetti intermedi posizionati in funzione della lunghezza reale dell’albero e della sua velocità di rotazione. I generatori elettrici indicati in fig.1 e in fig.3 sono in numero di quattro ma potrebbero anche essere solamente due (o anche di più) in funzione della taglia dell’aerogeneratore che si vorrà realizzare. E’ comunque chiaro che anche nel caso di due soli generatori elettrici le gear boxes (13) e (18) dovranno comunque essere in numero di due essendo ognuna di esse collegata a una delle due eliche. Nella fig.2 è riportata ingrandita e per maggior chiarezza la prima gear box (13) con il primo generatore elettrico (14). It should be remembered that in the drawings the shaft (4) does not rest on intermediate bearings but only on the final bearings of the reducer (18) even if in reality intermediate bearings positioned according to the real length of the shaft and its rotation speed must be provided. . The electric generators shown in fig. 1 and fig. 3 are four in number but could also be only two (or even more) depending on the size of the wind turbine to be built. However, it is clear that even in the case of only two electric generators, the gear boxes (13) and (18) must still be two in number as each of them is connected to one of the two propellers. Fig. 2 shows the first gear box (13) with the first electric generator (14) enlarged and for greater clarity.
Nella fig.3 è riportata una variante del sistema di generazione qui rivendicato; in questo caso infatti, senza nulla togliere alla funzionalità del sistema, la gear box (22) ha ingranaggi interni praticamente uguali alla (13) ma diversa è la carcassa poiché detta gear box (22) va posizionata in posizione intermedia tra i generatori (15) e (16) anziché alla estremità della catena cinematica così raffigurato in fig.1. In questo caso di fig.3, pertanto,i due generatori finali (23) non avranno alberi cavi perché non più necessari. Figure 3 shows a variant of the generation system claimed herein; in this case, in fact, without detracting from the functionality of the system, the gear box (22) has internal gears practically the same as (13) but the casing is different because said gear box (22) must be positioned in an intermediate position between the generators (15 ) and (16) instead of at the end of the kinematic chain thus depicted in fig. 1. In this case of fig. 3, therefore, the two final generators (23) will not have hollow shafts because they are no longer necessary.
Le alette di raffreddamento (12) sono indicate con andamento circonferenziale rispetto ai generatori di corrente ma potrebbero anche essere parallele all’asse principale della macchina in funzione di come si vorrà direzionare il flusso d’aria di raffreddamento. The cooling fins (12) are indicated with a circumferential trend with respect to the current generators but could also be parallel to the main axis of the machine depending on how you want to direct the cooling air flow.
